Our Anti-CA19-9/Sialyl Lewis A (sLeA) mouse monoclonal primary antibody from Antibodies Incorporated is produced in-house from hybridoma clone CA19-9-203. It detects human CA19-9/Sialyl Lewis A (sLeA), and is purified by Protein A chromatography. It is great for use in IHC, ICC, WB, ELISA.

Western blotting of SW1116 cell lysate using 0.2 ug/mL, 1 ug/mL, or 5 ug/mL Antibodies Incorporated mouse monoclonal anti-Sialyl Le (a) (19-9) antibody (MM-1003). MM-1003 mouse anti-Sialyl Le (a) (19-9) antibody recognizes endogenous Sialyl Le (a) (19-9) at 125 kDa.

Immunofluorescent staining of SW1116 cells using 5 ug/mL mouse monoclonal anti-Sialyl Le (a) (19-9) antibody (MM-1003) (green). The cells were mounted with Antibodies Incorporated Fluoroshield with DAPI mounting medium (Cat#AR-6501). DAPI nuclear stain (blue) shows cell nuclei. Anti-Sialyl-Le stains the membrane of SW1116 cells.

Target

CA19-9/Sialyl Lewis A (sLeA)

Target Description

CA19-9/ Sialyl Lewis a (sialyted lacto-N-fucopentose) (α-NeuNAc-(2→3)-β-D-Gal-(1→3)-(α-L-Fuc-[1→4])-D-GlcNAc, 3′-SLea) corresponds to blood group antigens. In normal tissue Sialyl Lewis a is present in ductal epithelium of the breast, kidney and salivary glands. This antigen is expressed is increased in all gastrointestinal carcinomas (stomach, intestine and pancreas) (1) While it is not useful to diagnose particular forms of cancer, specifically pancreatic cancer, it may be useful to monitor the results of treatment and to determine whether the disease may be recurring (3) Other causes for elevated CA19-9 levels include Mirizzi’s syndrome and other hepatobiliary diseases (2) In patients that do not have the Lewis antigen blood type (about 5% of the population), CA19-9 is not elevated in pancreatic cancer even with large tumors because they have a deficiency of fucosyltransferase that is needed to produce CA19-9 (1).
